Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519636, here are decompositions:

17 + 519619 = 519636
59 + 519577 = 519636
83 + 519553 = 519636
97 + 519539 = 519636
109 + 519527 = 519636
113 + 519523 = 519636
127 + 519509 = 519636
137 + 519499 = 519636

Showing the first eight; more decompositions exist.
